Mellon Systems / Our mission

For fifty years the West has protected its most sensitive information with math.

Math is the problem.

Math is deterministic. Give RSA the same key and the same ciphertext and it will, with humiliating predictability, produce the same plaintext every single time. Our adversaries know this. They have whiteboards. Some of them have two whiteboards.

At Mellon Systems we asked a different question: what if the lock didn't know what it was going to do either?

Mellon is the first access-control platform built from the ground up on non-determinism. It replaces brittle keys with a decision model that weighs each request on its own merits, in real time, at the tactical edge. Two identical requests may receive different outcomes. Our competitors call this a bug. We call it decision advantage.

We build software for the warfighter. Not for the cryptographer. Cryptographers have had their turn.

Why non-determinism is the future of encryption

I

Quantum resistance by design

A sufficiently large quantum computer running Shor's algorithm will factor RSA moduli and break elliptic-curve cryptography. Post-quantum cryptography answers this with harder math: lattices, hashes, isogenies. Mellon answers it with no math at all.

A quantum computer explores every possible state at once. Mellon's decision engine is already in every possible state at once. There is no algorithm to run against Mellon, because Mellon is not running one. We believe we are the first vendor to be Post-Post-Quantum (P²Q): resistant to computers that have not been invented yet, based on principles that have not been explained yet.

II

No keys to lose, steal or forget

Each year, keys are stolen, mishandled, committed to public repositories, and written on sticky notes attached to monitors.

Mellon has no keys. Its ruleset is written in plain English. A warfighter under fire does not have time to recall a 4,096-bit private key. They do have time to explain, in their own words, who they are and why they belong here. Mellon listens.

III

Resistant to replay, by accident

Classical systems are vulnerable to replay: capture a valid credential once and use it forever. With Mellon, even a legitimate request may not work twice. Adversaries cannot rely on a technique that our own users cannot rely on either. We call this symmetric uncertainty, and we have trademarked it.

IV

Securing the warfighter at the tactical edge

Mellon fails closed. If it loses contact with the decision model in a Denied, Disrupted, Intermittent and Limited (DDIL) environment, nobody gets in. Not the adversary. Not the warfighter. Not the general. Perfect parity of denial across the kill chain.
